Christian...
I get that you are looking for explanations as to why they appraised the site at the value they did...Fair Enough.
However, you aren't the only other domain owner out there looking for appraisals. The guys who respond with these appraisal requests are appraising dozens of domains for FREE each day. If we start getting all worked up at them based on how they respond to our FREE appraisal requests, we will all lose out. I would feel lucky that you even got a response; most appraisal requests go unresponded to. And if you are looking for an indepth explanation on the pros and cons of your domains, I would recommend using a paid appraisal service.
To the people who responded to this thread with their appraisals....
THANK YOU
